WorkSpace On-Demand 2.0 Feature for Windows ... - IBM Redbooks

define on a WorkSpace On-Demand server has its own unique workstation
record in RPL.MAP, which is created at the time you define the client.
Note
A client workstation may have more than one workstation record in the
RPL.MAP file. However, only one record may be active at any time.
When the server receives the FIND frame, it searches RPL.MAP for a
workstation record with a network address that matches the client’s address
contained within the FIND frame. If it finds a match, it responds to the client
with a FOUND frame. If it cannot find a match, it ignores the FIND frame.
After the server responds to the client with a FIND frame, and the client sends
a SEND.FILE.REQUEST frame, the server must determine how to assemble
the boot block to be sent to the client. The required information includes:
The type of network adapter installed in the client.
The operating system to download: DOS, OS/2, or Workspace
On-Demand.
For an OS/2 or WorkSpace On-Demand client, the FIT file that should
be included in the boot block.
The files that should make up the boot block.
Again, RPL.MAP plays a key role in this process. A client’s workstation record
in RPL.MAP contains certain information, such as the client’s workstation
name and the location of the FIT file, that should be included in the boot
block. In addition, the workstation record contains a key field (as shown in
Figure 7 on page 26) that references a server record.
RPL.MAP contains one server record for each client operating system
supported on the server and for each network adapter installed in the client
workstation. For example, there is one server record for an IBM Token-Ring
Adapter booting OS/2 Warp 4, and another record for an IBM Token-Ring
Adapter booting WorkSpace On-Demand 2.0.
The server record contains pointers to the remaining information required to
build the boot block. This information is actually contained in the boot block
definition (CNF) file, which is described in detail in Section Section 2.4.1.1,
“Boot block definition (CNF) file” on page 34.
